CVE-2026-56326

Nuxt versions 4.0.0 before 4.4.7 and 3.x before 3.21.7 contain a server-side open redirect vulnerability in navigateTo that fails to properly validate path-normalized payloads like /..//evil.com and /.//evil.com. Attackers can bypass external-host checks using path-normalization techniques to redirect users to attacker-controlled sites via the Location header or meta-refresh, enabling phishing and OAuth authorization-code theft.

Summary		(es) Las versiones de Nuxt 4.0.0 anteriores a la 4.4.7 y 3.x anteriores a la 3.21.7 contienen una vulnerabilidad de redirección abierta del lado del servidor en navigateTo que no valida correctamente las cargas útiles normalizadas por ruta como /.. / /evil.com y /.//evil.com. Los atacantes pueden eludir las comprobaciones de host externo utilizando técnicas de normalización de rutas para redirigir a los usuarios a sitios controlados por el atacante a través del encabezado Location o meta-refresh, lo que permite el phishing y el robo de códigos de autorización de OAuth.
